What 咞 means
It is a compatibility form of 咞, not a separate word. Unicode preserves it for conversion round trips with Taiwan's CNS 11643-1992, a multi-plane Chinese character encoding. The Unicode chart gives its source position as T4-235C. A round trip means converting text from that older encoding to Unicode and back without losing the original code position.
Why does 咞 become 咞?
Normalization changes it to 咞. Unicode treats them as equivalent forms of one character, so normalization rewrites 咞 as 咞. Software may normalize text when saving or comparing it, erasing the fact that the source used this compatibility codepoint.
To keep the compatibility glyph in normalized plain text, Unicode defines the standardized sequence 咞︀ (咞 followed by UFE00). The invisible variation selector tells the rendering software to use this specific form; the distinction appears only when the app and font support the sequence.

1Why does 咞 show as a box on some devices?
Not every system ships a font for the CJK Compatibility Ideographs Supplement block. Where none is installed, the character shows as an empty box; adding a font such as Noto fixes it. The character itself is still correct and copies correctly.
